Event entity monitoring network and method

A monitoring data processing device to monitor an event entity comprising:

• a data processor for generating first event data at a first level of detail used to identify the event entity, the first event data being an anonymized compression of raw information data collected by a sensor;
• wherein the monitoring data processing device is operable to receive a request to monitor an event entity at a second level of detail to generate second event data, wherein the second level of detail is more detailed than the first level of detail;
• and
• wherein the monitoring data processing device is operable to output the second event data comprising a notification to a data processing device being authorised to access the second event data having the second level of detail;
• or
• wherein the monitoring data processing device is operable to output the second event data comprising a notification to a data processing device having a policy to access the second event data having the second level of detail.

A recognition server to monitor an event entity comprising:

• input circuitry for receiving, at a first level of detail, first event data from at least one processing device in a monitored region, the first event data being an anonymized compression of raw information data collected by the least one data processing device;
• a processor for processing the first event data to identify the event entity inferred by the event data;
• responsive to the event entity matching a notification event, following a request, the input circuitry to receive, at a second level of detail, second event data from the at least one data processing device, wherein the second level of detail is more detailed than the first level of detail, and the recognition server to output a notification comprising the second event data having the second level of detail;
• and
• wherein outputting a notification comprising the event data having the second level of detail comprises a notification to a data processing device having authorisation to access the event data having the second level of detail;
• or
• wherein outputting a notification comprising the event data having the second level of detail comprises a notification to a data processing device having a policy to access the event data having the second level of detail.
